摘要:
 应用叶片离析法和石蜡制片技术,对猴樟、芳樟等几种樟树的叶片形态结构特征进行了研究,并运用聚类分析、相关性分析及隶属函数综合评价其抗寒性。结果表明:叶片解剖结构的叶片角质层、上下表皮、栅栏组织和海绵组织等13项指标聚为5类,依据相关指数的大小,从中筛选出角质层厚度、栅/海、细胞结构疏松度、叶脉突起度及海绵组织厚度等5项指标与樟树抗寒性密切相关。隶属函数法评判结果显示以猴樟的叶片解剖结构最有利于其抗寒,其次为芳樟、本樟和尾叶樟,而沉水樟叶片结构最不利于其耐寒。另外,发现细胞结构紧密度对几种樟树的排序结果与综合评价结果一致,也可用于樟树的耐寒性评价。
Abstract:
 The cold resistances of five camphor tree species (such as Cinnamomum camphora,C.bodinieri,C.micranthum,and so on) were evaluated by comprehensive appraisal index including clustering analysis,correlation analysis,and subordinate function value analysis based on the lamina anatomical structure and leaf epidermal characteristics.The results showed 13 indicators (such as the thicknesses of leaf cuticle,epidermis,palisade tissue,spongy tissue,etc.) were clustered into five categories.Indices such as cuticle thickness,the cell structure porosity,veins protruding,and spongy tissue thickness that were found to be closely correlated to the cold resistance were selected based on the size of the index.Membership function evaluation demonstrated that the leaf anatomical structure of C.bodinieri was the most beneficial to its cold resistance,followed by linalool-type,camphor-type,and C.camphora,but C.micranthum leaf structure however,was the most unfavorable to its cold resistance.
